Disick and Richie looked equally stylish on Thursday while attending an art exhibition by Alec Monopoly and David Yarrow. For this soiree, the model opted for a more casual ensemble, which consisted of a black tank top and high-waisted pants. Disick donned a pair of light wash skinnies and a striped shirt, placing his arms around his girlfriend and Monopoly for a snap inside the pop-up, presented by Haute Living.
